iOS 警告

利用一个特定的标题和消息来启动一个警告对话框。

提供一个可选按钮的列表。点击任何按钮触发各自的按下回调动作，并且忽略警告。在默认情况下，只有一个按钮是“OK”按钮。列表中最后一个按钮被视为“主”按钮，它被用粗体显示出来了。

    AlertIOS.alert(
      'Foo Title',
      'My Alert Msg',
      [
        {text: 'Foo', onPress: () => console.log('Foo Pressed!')},
        {text: 'Bar', onPress: () => console.log('Bar Pressed!')},
      ]
    )}

方法

static alert(title: string, message?: string, buttons?: Array<{ text: ?string; onPress: ?Function; }>)
